Add a second WAN port using a LAN port for mwan3 not issuing DHCP addresses

I've got an RBM33G Routerboard and seem to be having trouble with a second WAN port in which I used an open LAN to configure. Everything seems to work find, except I can't get dnsmasq and VLANs to issue dynamic IP addresses which are connected to the now single LAN port.

A second pair of eyes greatly appreciated.

Posting the /etc/config/network file contents I've also noticed that even though changes have been made via Luci, some configs are left behind or in place. Is this to be expected?

I'm going to backup config, and do a reload and start with just a single LAN being changed to a WAN with a single VLAN and will follow this up with attaching new configs - apologies for all the above info, I will do my best to focus the attention where it matters to follow. Thanks so much for anyone's input.

reinstalled and configured everything accept for mwan3 and all is working as expected. New network configure below. Installing mwan3 now and will follow-up if DHCP quits working again. However, note that:
option vlan '3' was placed placed in:
config switch_vlan
option device 'switch0'
option vlan '3'
option ports '6t 1'
option vid '20'
which I don't think is correct. VOX interfaces vlan is 3 and I did not set switch_vlan option vlan to 3. It may be a Luci thing, I'm going to test setting it to 20 manually in /etc/config/network.

Confirmed DHCP is working including VLAN designations:

1602619179 00:15:65:e4:66:22 10.3.10.236 SIP-T27G 01:00:15:65:e4:66:22

Mixing tagged and untagged frames on the same interface can cause issues. I remember from a previous Mikrotik I had running with OpenWrt everything was tagged.

Other than that you have a index number called vlan and the vlan id (which is the actual vlan used) called vid.

Thanks for the feedback @trendy Still confused though, so is option vlan an index? Is that its purpose? If so, where does option vid stand? I''ve since made the following adjustments manually and don't see any issues thus far. I'm needing vlan 3 for phones and option 132 dns, another rabbit hole.

Note to self and others, don't ever rely on Luci to sysconfig update and save your config - the save config checkbox does not always work. Just had to reconfigure everything "again". Always conduct your sysconfig update on a refresh reload before configuring anything.


Does this answer your question?

Having the ability to rename Luci titles in switch config would be great for those getting creative with interfaces as well, another rabbit hole. I'm about to install mwan3, if things go into show stopper mode again, I think I'm going to end-game mode and making use of bonding on the WANS. Again, thank you @trendy

Crystallized, thank you.

Crystal, thank you! Forgive my frustration if its projecting, its only due to my ignorance.

This must be some hardcoded setting in Luci, to follow the labeling on the device. Maybe you can search in the Luci files or someone else might have an idea where is it stored.

@trendy you mention your experience with Mikrotik and not to mix. I've set VOX as tagged across the board, is this what you're referring to - reading your link I see mention of some hardware only accommodate 4bit on VLANS. Would it be safer for me to go with setting WANB at 3 and setting option 132 vid=another vlan idea for example in dnsmasq and/or options on interfaces?

Thought about hardcoded the html/css but surely it would be overwritten, I'll dig in on Luci threads thanks again and again.

I suppose that you have a managed switch connected to the Mikrotik. At least I had one and all the ports which had vlan tags, were only sending tagged frames. So if you want to use vlan 3 tagged on all ports, make all vlans tagged on all ports and let the switch drop or add the vlan id depending on the capabilities of the host.

I see, this is exactly how I've got our upstream LAN switch configured (all ports tagged) CRS328 MT running SWOS. All phones are configured broadcast option 132, router RBM33G receives and knows to assign VLAN3 to phones. Thank you for the reassurance and worry shun!

Then make sure you are running some kind of per vlan stp on the switch as you have more than 1 ports on the same vlan and you'll have a bridge loop.

Woah, moment please...



I believe RSTP tab and its auto settings cover potential loops? Please let me know if more screen in shots are needed. Honestly the only reason I assigned VLAN20 to WANB was to get it out of scope of future VLAN variables needed.

I am not familiar with Mikrotik's SwOS, so I cannot say for sure it is right or wrong. But it seems that you generally allow all tagged vlans and you have default vlan id for untagged frames. The switch looks like it is root bridge and some ports are disabled to prevent loops.

Thanks for your insight, I'd like to mark a post as solution on your behalf just not sure which one to choose :slight_smile:

I'm going to try installing mwan3 now to see what happens, hopefully I just had something a muck elsewhere in previous config regarding "not issuing DHCP addresses" original issue.

Nevertheless, if things go wrong on mwan3 install I'll revert to making use of bonding on the WANS for redundancy and mark one of your post as solution.

Maybe the one that was the most helpful. :slight_smile:

Final follow-up, regarding making use of mwan3 pay special attention to naming schemas of interfaces as they seem to be case sensitive in the eyes of mwan3, not so much in the eyes of openwrt itself. If you've already configured interfaces via Luci, then modify /etc/config/network directly to make case changes. Again, thank you @trendy

OpenWrt, as a linux derivative, is case sensitive in general.
